Definitions
- the invention concerns a gearbox control system.
- Gearboxes can be individually adapted to different types of vehicles with the aid of gearbox control systems.
- the gearbox control system makes possible the integration of functions that are relevant to comfort, safety, and service.
- the shifting comfort is generally in the foreground, even though it is directly felt by the driver.
- Other important functions concern the shift point control, safety, and diagnosis. Shifting comfort is still quite important.
- An excellent shifting comfort, which remains constant during the entire service life of the gearbox, is the main duty of the gearbox control system.
- the shifting comfort is influenced by a variety of parameters which are described in the ATZ Automobiltechnische Zeitschrift 93 (1991).
- a constant friction value level can be achieved.
- the shifting pressure of the multi-plate clutches or of the brake band is controlled in dependence upon parameters such as gear stage, engine speed, throttle flap angle for thrust-traction recognition, gearbox output speed, engine speed, gearbox temperature, and engine temperature in such a way that a uniform shifting operation always takes place.
- an adaptive pressure control takes place; that is, the deviations from specific parameters are automatically corrected during the operation time of the gearbox.
- the response times or gliding times are permanently measured and average response times are determined from several shifting operations. If there is a deviation of the average response time from desired response times dependent from the load and engine speed, the clutch pressure is changed until the desired response time is reached.
- a gearbox control system for a motor vehicle drive with an automatic gearbox which makes it possible to adapt shifting characteristic lines.
- the control system has a characteristic line storage in which the shifting points of the gearbox are stored, and additional devices can be modified by means of which the shifting points in dependence upon the driving parameters.
- the shifting arrangement Based on an evaluation of the output speed of the gearbox, carried out at successive time in intervals, the shifting arrangement generates an output signal by means of which the shifting characteristic lines can be adapted to the load condition of the motor vehicle.
- This control system does not make possible, however, a shifting pressure change and thus also the gearbox torque transmission behavior cannot be adapted to the long-term changes.
- the basic object of the invention is attained by means of a gearbox control system of the type described above.
- This reference gearbox is implemented in the gearbox control system in the form of a gearbox model.
- the calculated shifting pressure is sent by means of a pressure control valve to the gearbox and, at the same time, fed to the reference gearbox in the gearbox control system.
- the gearbox control system continuously measures the previously defined parameters of the gearbox and compares them to the corresponding parameters of the reference gearbox.
- the gearbox control system determines the deviations between the parameters of the real gearbox and the reference gearbox and calculates a pressure correction value therefrom which is taken into consideration during the next shifting operation, and is superimposed on the real gearbox in such a way the behavior of the real gearbox and the reference gearbox converge. This operation is repeated for each further shifting operation until the deviations between the real gearbox and the reference gearbox have been reduced to a minimum. In an ideal case, a correspondence between the real gearbox and the reference gearbox results.
- the adaptation of the real gearbox and the reference gearbox can take place, to a great extent, independently from the operating condition. All the occurring known systematic influencing variables can be integrated in the reference gearbox and can thus be taken into account during operation.
- load conditions, shift points, accelerations, and temperatures can be incorporated in the reference gearbox.
- the adaptation of the real gearbox and reference gearbox can also take place independently of the gradient of the shifting pressure.
- the shifting pressure can, therefore, also include any desired components of a pressure control or a superimposed pressure control, without this having an effect on the adaptation of the real gearbox to the reference gearbox.
- FIG. 1 shows a schematic of a gearbox control system of the invention.
- a real gearbox 1 is characterized by the actual condition which is defined by parameters, such as, the input speed 2 and the input torque 3 as well as the output speed 4 and the output torque 5 .
- Disturbance variables 6 are added to them, which influence the real gearbox.
- Illustrative examples of the parameters and of disturbance variables 6 are presented in ATZ Automobiltechnische Zeiftschrift 95 (1993), “Die Adaptive Getriebe Kunststoffung fur BMW-Automobile”, pgs. 420–434 , ATZ Automobiltechnische Zeitschrift 96 (1994), “Intelligente Steuerung von Automatikgetrieben Wegtechnischen Wegtechnischmaschinenik”, pgs 228–235 and in U.S. Pat. No. 5,157,609 issued Oct. 20, 1992 to Stehle et al.
- a desired condition is determined from the input speed 2 and the input torque 3 in an ideal reference gearbox 7 which is integrated, as a gearbox model, in the gearbox control system 8 .
- a shifting pressure 9 is calculated, which is further processed with the deviation from the actual condition and desired condition in the gearbox control system 8 to a pressure correction value 10 .
- error functions can be integrated in the calculation of the pressure correction value 10 .
